The invention relates to a polyamide compound and a use thereof. Specifically, the invention relates to a type of polyamide compound (which preferably comprise one or more amide bonds formed by condensation of same or different L-amino acids or D-amino acids), or stereoisomers, crystalline polymorphs, solvates, metabolites, prodrugs or pharmaceutically acceptable salts or esters thereof, or pharmaceutical compositions thereof, as well as a method for preparing the polyamide compound and a use thereof in the prevention or treatment of diseases associated with κ-opioid receptor. The polyamide compound of the invention has excellent κ-opioid receptor agonistic activity and hydrophilicity, thus having a lesser ability of penetrating the blood-brain barrier and a lower capacity for entering the brain. The compound of the invention has higher selectivity for a κ-opioid receptor, lower addictiveness, improved pharmacokinetic properties, and improved safety (lower toxicity and/or fewer side effects), good patient compliance, and/or lesser propensity for developing tolerance, among other excellent medicinal properties.
本发明涉及一种聚酰胺化合物及其用途。具体地说,本发明涉及一种聚酰胺化合物(优选包括由相同或不同的 L-氨基酸或 D-氨基酸缩合形成的一个或多个酰胺键),或其立体异构体、结晶多晶体、溶解物、代谢物、原药或药学上可接受的盐或酯,或其药物组合物,以及制备该聚酰胺化合物的方法及其在预防或治疗与 κ-阿片受体相关的疾病中的用途。本发明的聚酰胺化合物具有优异的κ-阿片受体激动活性和亲水性,因此穿透血脑屏障的能力较弱,进入大脑的能力较低。本发明化合物对κ-阿片受体具有更高的选择性、更低的成瘾性、更好的药代动力学特性、更好的安全性(更低的毒性和/或更少的副作用)、良好的患者依从性和/或更低的产生耐受性的倾向,以及其他优异的药用特性。
